The Intergovernmental Panel on Climate Change (IPCC) released the third part of its sixth assessment report in April 2022. The report states that the Earth's climate is rapidly deteriorating but also presents solutions.The report cites LUT University's research on ambitious mitigation pathways and novel technology options.

According to the IPCC's latest working group report, we need to work fast to mitigate climate change and capture carbon from the atmosphere. Businesses, communities and individuals need to take action. Governments need to apply strong political and economic steering to support sustainability.

The goal of the international Paris Agreement is to limit global warming to well below 2, preferably to 1.5 degrees Celsius, compared to pre-industrial levels. To achieve this goal, greenhouse gases of a human origin and carbon sinks should be balanced by the latter half of this century.

Every few years, the IPCC complies an assessment report on scientific data on climate change, its impacts, and possibilities to mitigate and adjust to it.

LUT's scientific solutions

The third part of the most recent IPCC assessment report substantially draws on LUT University's ambitious research. The report refers to 38 scientific papers by LUT and cites them 54 times overall. LUT examines the mitigation of climate change from the perspectives of technology, economics, society and the environment.

According to its strategy, LUT seeks solutions for clean energy, water and air and sustainable business by applying its expertise in technology and business.

Esa Vakkilainen is one of the peer reviewers of the report, an energy technology professor at LUT and a member of the Research Council for Natural Sciences and Engineering of the Academy of Finland. Professor Vakkilainen emphasizes the utilization of bioenergy as an essential way to promote sustainable development.

"Especially biowaste and agriculture and forestry by-products can be used as raw materials for fuels to replace fossil products, such as textiles and packaging, all over the world. The utilization of biomass already in circulation promotes each country's self-sufficiency, but the raw material also has a global market," Vakkilainen points out.

LUT's research on the energy transition and power-to-x (PtX or P2X) is cited in the report. P2X technologies play a key role in creating a carbon-neutral world. They enable producing synthetic electricity-based e-fuels, e-chemicals or fertilizers from air and water with renewable electricity.
The report closely cites LUT's research on the direct air capture of carbon dioxide (CO2) for carbon-neutral e-fuels and net-negative CO2 emissions.

Renewable electricity can be generated with wind and solar power, for example. Christian Breyer, LUT University's solar economy professor and a member of the Finnish national IPCC group, and his research team have modelled how countries, entire continents and the world could give up fossil fuels by using tools such as P2X technologies.

"The rapidly declining unit costs of solar and wind power, batteries, electrolysers, and various PtX technologies will enable a technically feasible and economically viable fully sustainable energy system by 2050. This is particularly relevant for the Global South, where billions of energy-hungry people are pursuing a higher standard of living," Breyer sums up.

Focus on systems and individuals

The IPCC report also underlines the individual person's strong possibilities to make a difference. Choices related to issues such as food and transport may help curb climate change.

LUT University's sustainability science research team was the world's first to launch a personal carbon trading scheme. The scheme was piloted in the city of Lahti, revealing that a carbon trading app and cutting back on the use of private cars could contribute to the reduction of greenhouse gas emissions.

Also changes to other consumer behaviours and habits can impact sustainability and increase the demand for responsible products and services.

Solutions that mitigate climate change should aim for systemic sustainability and global equity. People should avoid actions that promote the loss of biodiversity or the extreme effects of climate change, such as natural disasters or climate migration.

In this video, LUT University explains how systemic change is connected to solving the climate crisis.
